Jackson, who made his international debut in 2010, has won 23 caps for Scotland and follows his fellow Test half-back Greig Laidlaw into the Premiership after Laidlaw recently agreed terms with Gloucester.

" I am very excited about joining Wasps," Jackson said.

"I have been at Glasgow a long time now, but I am now relishing this new challenge that lies ahead.

And Wasps rugby director David Young added: " I have been very impressed with what I have seen of Ruaridh, and I am looking forward to welcoming him to the club.

"He will add to the quality pool of 10s we already have, and the competition for that position next season will be very strong."
